1. DRY MIX Notes Independent/ Manipulated
the one that is changed by the scientist to test a hypothesis
To insure a fair test, a good experiment has only one independent variable
Ask “What am I changing on purpose?”
Is graphed on X- axis

2. Dependent/ Responding
Factor that changes because of the independent variable
The new value of the dependent variable is caused by and depends on the value of the independent variable
Ask “What am I measuring?”
Graphed on the Y - axis

3. Control
quantities that a scientist wants to remain constant, and he must observe them as carefully as the dependent variables
Ask “What am I keeping the same?”
